CPANM is the most convenient way to install Perl modules. Automatic Download installation Dependency pack. Using the CPAN shell or download source package to install the module, encountered a lot of dependencies, very headache. Here's one example:
Installing the MongoDB module
Copy Code code as follows:
# Perl makefile.pl
Warning:prerequisite class::method::modifiers 0 not found.
Warning:prerequisite data::types 0 not found.
Warning:prerequisite DateTime 0 not found.
Warning:prerequisite Datetime::tiny 0 not found.
Warning:prerequisite extutils::makemaker 6.59 not found. We have 6.30.
Warning:prerequisite file::slurp 0 not found.
Warning:prerequisite file::temp 0.17 not found. We have 0.16.
Warning:prerequisite JSON 0 not found.
Warning:prerequisite Moose 0 not found.
Warning:prerequisite test::exception 0 not found.
Warning:prerequisite Test::warn 0 not found.
Warning:prerequisite Tie::ixhash 0 not found.
Warning:prerequisite Try::tiny 0 not found.
Warning:prerequisite Boolean 0 not found.
Writing Makefile for MongoDB
1. Install Cpanm
CPANM is actually an executable file. Download it to the bin directory, and then add execution permissions.
Copy Code code as follows:
# wget http:
Xrl.us/cpanm-o/usr/bin/cpanm; chmod +X/USR/BIN/CPANM
2. Use CPANM installation module
Copy Code code as follows:
# cpanm-h
-V,--verbose turns on chatty output
-Q,--Quiet turns off the most output
--interactive Open Interactive configuration (required for Task:: Modules)
-F,--Force forced installation
-N,--notest do not run unit tests
--test-only only Test not installed
-S,--sudo sudo to run install commands
--installdeps only Install dependent modules
--showdeps Only show dependency information
--reinstall Reinstall
--MIRROR Specifies the mirror URL (e.g. http://cpan.cpantesters.org/)
--mirror-only downloads only from mirrors
--prompt prompt when Configure/build/test fails
-L,--local-lib Specify the install base to install modules
-L,--local-lib-contained Specify the install base to install all Non-core modules
--self-contained Install all Non-core modules, even if they ' re already installed.
--auto-cleanup number of days, CPANM ' s work directories expire in. Defaults to 7
Examples:
Cpanm Test::More # Install Test::More
CPANM miyagawa/plack-0.99_05.tar.gz # Full distribution path
Cpanm http://example.org/LDS/CGI.pm-3.20.tar.gz # Install from URL
Cpanm ~/dists/mycompany-enterprise-1.00.tar.gz # Install from a local file
Cpanm--interactive Task::kensho # Configure interactively
Cpanm. # Install from local directory
Cpanm--installdeps. # Install all of the Deps for the current directory
Cpanm-l extlib Plack # Install Plack and all Non-core deps to Extlib
CPANM--mirror Http://cpan.cpantesters.org/DBI # Use the fast-syncing mirror
Parameter name is directly the module name
For example, install the MongoDB module
Copy Code code as follows:
# CPANM MongoDB
--> Working on MongoDB
Fetching http://www.cpan.org/authors/id/F/FR/FRIEDO/MongoDB-0.702.0.tar.gz ... Ok
Configuring MongoDB-0.702.0 ... Ok
==> Found dependencies:datetime, Tie::ixhash, Data::types, Datetime::tiny, Class::method::modifiers, Boolean, Moose , File::slurp, Try::tiny, Test::exception, Extutils::makemaker, Test::warn, File::temp, JSON
--> Working on DateTime
.//Auto-Resolve dependent module
To speed up downloading, you can specify that you want to use mirroring and download only from mirrors:
Copy Code code as follows:
# CPANM--mirror http:
Mirrors.163.com/cpan--mirror-only MongoDB
3. Delete Module
Install App::p muninstall module:
Copy Code code as follows:
# CPANM APP::p muninstall
4. Delete Module
Copy Code code as follows:
MongoDB.so:undefined Symbol:heutf8 Problem solution See: http://www.jb51.net/article/56285.htm
